MF/HF transceiver design varies by manufacturer. Some units require manual entry of specific frequencies for specialized operations, while others utilize internal databases to recall pre-programmed ITU channels. Operators must be familiar with their specific equipment's interface, as either method may be the primary means of frequency selection depending on the model.
